I learned traditional techniques first as well, then moved toward digital. I recommend the same for you. Digital scales better, prints better, is impossible to lose with the appropriate forethought, and there are several things that simply can't be done outside a digital environment.
I suggest getting a pen tablet and a copy of manga studio 4 EX (CHEAP) or 5 Pro. The pen tablet is the most expensive item you'll invest in, but getting a decent one is well worth the money. Think of it as buying a year's worth of bristol in one shot. It's less painful.
The Wacom's are still the best. If you want a display pen tablet, however, they're out of just about everyone's price range, as one large enough to be functional is as much as a decent car. Ugee made a decent one a few years ago, which is what I use. There are several other asian manufacturers in that pricepoint, and you'd be well off to research reviews on Amazon for who's making the best value device at the moment.
There will be a learning curve when purchasing a non-display type pen tablet. Be prepared for it, though it isn't as steep as one might think. They are useful, and I still own mine and use it occasionally. Wacom is very, very good in these, and reasonable. Trouble-free support is invaluable.
As to software, I've used Corel, PS, and MS, and I prefer MS. It's a personal choice, and some just like PS or Corel. The EX or Pro versions of Manga Studio, however, are well-tailored to comics/manga, and support vector layers, 3D, 2D processing, filters, tones, and just about anything one would want. I'm still learning new functions. I adore it. 4 EX is still available from some sellers and is unbelievably cheap. It is also, in ways, more functional than 5 pro. If you're on a budget, 4 EX is THE way.
As to your last question, would I read a comic with art at your skill level? I read several that don't look as good as the samples provided. For me, it's more about content with a nod toward quality. I think you'll find most people feel the same or similar.
